Pursuing it with eager feet / Until it joins some larger way

Hamlet’s friend Horatio quips, “I knew you must be edified by the margent ere you had done.” A colloquial version of that would be, “I knew you would need an explanatory marginal note to figure that one out.” “Edified by the margent:” this is an allusion to a statement in the preface to the Geneva Bible, where the editors tell the readers that for “good purpose and edification” they “have in the margent noted” certain things. “Edification … in the margent;” “edified by the margent.” (http://www.reformation21.org/articles/shakespeare-and-the-geneva-bible.php)
